Question 1

How to use clipboardy in a browser?

Accepted Answer

Clipboardy works in browsers via the native Clipboard API, but only in secure contexts like HTTPS. Use the asynchronous methods (write, read), as synchronous ones are not available. Ensure your site is served over HTTPS for compatibility.

Question 2

Does clipboardy work on Linux with Wayland?

Accepted Answer

Yes, clipboardy automatically detects Wayland sessions and uses wl-clipboard if installed. If not available, it falls back to X11 tools. Install wl-clipboard via your distribution's package manager for seamless operation.

Question 3

Clipboardy vs Electron's clipboard API: which is better?

Accepted Answer

Clipboardy is ideal for cross-platform Node.js apps outside Electron, as it abstracts OS differences. For Electron apps, the built-in clipboard API is more integrated and lightweight, but clipboardy can be useful if you need consistency with non-Electron codebases.

Question 4

Can I copy images to the clipboard on Windows with clipboardy?

Accepted Answer

No, image clipboard support is currently limited to macOS. On Windows, methods like writeImages are no-ops, so you'll need alternative libraries or platform-specific solutions for image handling.

Question 5

How to handle errors when clipboard access fails in Node.js?

Accepted Answer

Use try-catch blocks for async methods or error handling for sync calls. Common issues include missing tools or permissions; clipboardy may throw errors if fallbacks fail, so implement robust error management in your code.

Question 6

Is clipboardy secure for copying sensitive data?

Accepted Answer

Clipboardy relies on system clipboard APIs, which may expose data to other applications. In browsers, it uses the Clipboard API with user permission prompts. For sensitive data, consider encrypting content or using secure alternatives to mitigate risks.
